20" f3.7 Large Open Truss Kreige style Dobsonian

This is a Superb approx 20" Open Truss Dobsonian telescope, complete except for optics. Currently set up for F3.7 mirror but easy modification to any focal length by adding longer truss tubes. Has duel speed Moonlight focuser, Telrad, 27 point floatation cell, 80mm colour coded finder to match cage tubes & focuser, steel wheel barrow handles, custom spandex light shroud, mirror finished wood work. Built to a very high specification with dovetailed mirror box, cost in excess of £2,600 to have built without optics 2 years ago. The beauty of this scope is you do not need to climb a ladder in the dark as the focused is at the perfect height for most people.

Hmm... and the optics would cost...?

Well into four figures, I'd imagine. Assuming you could find someone to buy them from.

Urgh. Imagine trying to get the collimation perfect on that !
